We spent our last days before flying home in Longyearbyen. Longyearbyen is a small city (about the size of Pomona College). The main industries there are mining, a university and tourism. 
Here are Derek and Julia standing by the University Centre in Svalbard (UNIS)

Julia and Derek in front of the water pipes that are above the frozen ground and have to be heated during winter.
We had a magical midnight hike around town in the falling snow.
Here is a view of an abandoned mine building on the hillside covered in a light dusting of snow.
The Norwegians get acclimated to cold weather early in life. The babies take their naps swaddled in their carriages outside.
Here is a baby sleeping outside the market in a light rain/snow (we confirmed that the carriage was occupied).
The little auks breeding around Longyearbyen had gone south long before we arrived. The only little auk we saw was the one that Derek made out of snow.
